Übersicht MarGrid is grating designed to be placed above MarPak in the Biomedia System and is ideal as a walking surface and a maintenance platform for your waste water treatment application. With complete coverage, MarDek serves to further protect the media surface from weathering and impact.


MarGrid is rugged and heavy duty, not like thin-section thermoplastic products. The thick-section fiberglass composite is designed to take extensive abuse and last for years and years. The grating panels can be easily cut and modified to fit almost any plant requirement.
